To all whom it may concern:

Be it known that l, Mrnns P. FILLING- IIAM, a citizen of the UnitedStates, residing at Ansonia. in the county of New Haven and State o1(onnccticut, have invented a new and useful Improvement inVulcaniaing-li resses; and l do hereby decl-are the following. whentaken in connection with the accompanying drawings and the letters ci".reference marked thereon. to be a t'ull, clear, and exact. descriptionof the same7 and which said drawings constitute part of thisspecification, and representa in-` Figure 1 a side view of a pressconstructed in accordance with my invention. F ig. 2 a sectional viewof' the same with the press tank closed and the table in a depressedposition. 3 a similar View with the press tank lowered and the tableraised Wit-h the cap supported above it. Fig. t a top View showing thecap in its locked 'position with relation to the tie-rods. Fig. 5 a planview of the head and cover. Fig. 6 a sectional view ot' the ram cylindershowing a top view of the piston thereon. Fig. 7 a vertical sectionalview of the piston. Fig. 8 a sectional Fig. 9 a plan view of the headformed with. an elliptical opening. Fig. 10 a plan view of an ellipticalcover therefor. Fig. 11 shows two hars pivoted together and adapted tobe used a substitute forthe cover shown in Fig. 10.

This invention relates to a vulcanizing press of the type in whichhydraulic pres sure is enzployed and in Which rubber products may bevulcanized, and particularly a press 'in whichtires toin automobiles andotherv vehicles may be .vulcanized; the object of the invention being asimple construction which facilitates the charging and emptying of thepressgrsid in which the necessary power is obtained with the minimumamount of strain on the mechanism; and the invention' consists in theconstruction hereinparticularly recited in In carrying out my invention,I employ a press tank 2 of suitable size which is adapted to move'vertically on a ram cylinder 3 which cylinder passes through apiston-box l and is supported by a base 5.y Around the 'upper end of thetank 2 is a head 6 which is connected vwith the piston-box 4 by fourtie-rods 7.- The upper end of the rain cyl- ,ends of the tierods 7,

Aformed integral with inder 3 forms a table support 8 upon which a table9 rests, and this table is mountedat the upper end of a ram 10 whichextends downward into the rain cylinder to which water is admittedthrough a port 11 near the base 5. ln the head 6 is a central opening12, and in the edge of the opening are a series of notches 13 more orless in number. Through the opening a cover '14 may be inserted thecover being formed with outwardly projecting fingers 15 corresponding inposition to the notches 13 so that the cover may be passed through thehead7 and when passed through may be turned so that the lingers 15engage with the edge of the cover between the notches 18. Resting uponthe head is a cap 16 which is formed with four holes 17 of sufficientsize to allow the cap to pass over the nuts 18 on the upper and openinginto these holes 17 are slots 19 which permit the cap to be rotatedslight-ly'so as to -pass between the nuts 18 to firmly interlock the capwith the head. connected to the under face of the cap 1G by screws 20passing upward through the cover andinto the cap so that the cover mayhave a slight vertical movement with respect to the cap which will beturned with it and so that when the cap is turned to interlock with thenuts 18 the cover will be turned to lock with the head (i. To supportthe cover attach to each of the tie-rods 7 a bracket 21, and the coverisformed with four downwardly extending fingers 22 in the lower part ofwhich rollers 23 are mounted and adapted to ride on the brackets. One ofthe brackets 24, however, will be formed with a rack 25 and the roller2G adjacent thereto will he formed as a pinion to engage with the rackand is rigidly secured to a short shaft 27 to the outer end of which isfixed a hand-wheel 28 and so that by turning the hand-wheel thc cap willbe caused to rotate. Preferably and as herein shown, the cap will beprovided with asuspension hook 29 b which the cap may be supported fromany convenient point as will hereinafter appear.

0n the ram cylinder within the pistonhox f1 is a: piston vwhich consistsof a ring 30 resting at its lower end on a collar 31 the ram ,cylinder 3which is also formed with an annular lip 32 above the collar which lipis formed with notches 33 to receive bolts 34 t-he heads of Preferablythe cover 14 will be which rest between the lip 32 and the collar 31,the bolts extending up through the ring 30, and this is held in place bya removable collar35 formed with the round holes 36 adapted to set over-the nuts 37 on the bolts 34, and with slots 38 opening from said holesso that if the removable collar is slightly turned it will beinterloeked with the nuts. The removable collar will also be providedwith perforations 39 which when the collar is turned to clear the nuts37, will register with threaded holes 40 into which screw eyes may beturned and by which the ring` may be lifted out of the p1s ton-box, itbeing understood that the holes in the rin through which the bolts passwill besu "ciently large to clear the nuts 37.

In the bottom of lthe piston-box is a port 41 for the admission ofwater; and 1n the top of the box is a port 42, the first entering belowthe piston, and the other above it. The ends of the piston-boX will beclosed by covers 43, 44, and these covers as well as the bottom of thepress tank will be provided with a stuffing box 45 of usual form.Between the head and the cap, I arrange a packing-ring ,46, between'thetable and the t table-support a packing-ring 47, andaround the ring 30 Iinsert two leather packings 48.

The tank 2 may be surrounded by a jacket 49 into which steam may beadmitted so as to vulcanize by dry process.

To load the press, the cap 16 is turned so as to clear the nuts 18, andthis turning of the cap turns the cover 14 so as to disengage it fromthe head 6. Water is then admitted through the port 41 into the pisyton-box below the piston, and this depresses the piston-box. drawing thepress tank downward, and it is depressed until the table 9 is exposed atthe top of the tank. Mold boxes 50 are then placed upon the table, oneon the top of the other if a number are to be inserted; and when thedesired number -of molds are placed upon the table the tank is raised byadmitting water through the port 42 above the piston and letting waterescape through the port 41 below the piston so as to lift the piston-boxand raise the press-tank. The .cover` and the cap are then restored toplace. If there is then a space between the upper mold and the cover,the ram 10 will be'raised by admitting the water through the port .11 soas to crowd the molds up against the cover and hold the cover up againstthe under face of the head. Tater will then again be admitted throughthe port 4l drawing the press tank downward, and forcing the cover tothe top of the uppermost mold, which molds will be compressed betweenthe cover and the head with a force equal to the weight of the tankl andpress box in addition vto vthe hydraulic pressure. Steam is Jthenadmitted to the press tank in the usual way'through the pipe 51 tovuleanize thef articles in the press. When properly cured the cap andcover are againremoved|` ano the press depressed to permit the molds tobe readily removed. It `will be noted that this construction permits themold to be inserted into the top of the press tanker transferred from asuitable platform directly to the table as the table may be moved up ordown independent of the press tank.

Instead of connecting the eover 14 with theoap 16, it may be formedindependent thereof, and the opening in the head may be elliptical toreceive an elliptical cover 52. By turning this cover, it is readilyinserted through the head and turned so that its edges engage with theunderface of the.

head, or instead of forming the cover as in the form of a 'disk or4plate it may be in the form oftwo bars 53 and 54 which are pivotedtogether so that they may be turned to permit the bars to be insertedthrough the hole in the head, and then turned at right angles to engagewith the under face of the head. f
